My toaster oven converted to tempering oven started getting a funny smell and so i killed power to it. I know i fried something internally. I never really liked it, and want to build something else. I found that coffee makers have 120v elements in the 1400w area and are nice and compact, and also covered with nonconductive material which makes it easy to work with. I make small folder parts and a 4" diameter coil like this would be about perfect.

I am looking to make a compact tempering oven to save benchtop space. Thinking about putting one of these in a 6" tube, making a wire rack i can secure above it, wrap tube with inswool, stuff the whole package inside a 8" tube, weld some legs onto the 8" tube, and then top it all off with a couple firebricks. I want this thing to easily hit 650F.

Any better ideas?
 
it looks like element was designed to heat water. i think if plugged in without water, it will glow for a minute then melt. spend $50 at walmart and get a new toaster oven and save the heart ache
 
Ah, i did not consider that. I really dont want to go the toaster oven route again. I just really want something small and simple. I may try an oven range element. The small ones are usually around 1200watts.
 
Buy linear oven elements and make a box from hard rockwool board or similar. The insulation will be much cheaper than inswool or insboard and is actually a better (but lower temp) insulator. Far easier than building a full oven. $15 pid and you are off to the races.
 
Search engines turn up lots of large oven elements and water heater elements. All the manufacturers like durex and kanthal require you to call and speak to a "specialist". I think that is code for $$$$. I would extract the elements from the toaster but i really just have my mind set on a small rig, i dont want a 10"x14" long thing taking up almost a quarter of my main finishing workarea.

Any good suppliers with an online store?
 
I would take a look at a quartz rod heating element. It would be easy to run with a PID. eBay has lots of them.
 
I have been looking at an Eastwood "bench top powder coating oven." Sure, its a huge toaster oven, but it goes to 450F and is big enough that you can fit like a 20 inch OAL blade on the hypotenuse, so to speak. I am giving that serious thought as my shop is not at my house, so no quick snap temper in the kitchen oven and my HT oven takes a LONG time to cool down from 1500F. Best part is that it is cheap. I may have to spring for one.
